This invention, in general, relates to multiple-head winding machines and, in particular, to space-savlng arrangements of the bobbin heads on the machine frames.

- With the increasing rate of production in the manufacture of synthetic thread, the space problem becomes especially important in those cases in which the body of thread, which is first formed on the spinning machine,

cannot be used without further processing of the thread,

the machine, or else in two such rows along the length. of the machine, running next to one another with the .bobbins in each case extending the same direction, projecting at a right angle on the one side and on the other side of the machine, or even in several such double rows in ..tiers, one above the other, in which arrangement the bobbin heads are driven either in common, in groups of several bobbin heads or singly.

A disadvantage in the tending of such machines with double rows of bobbin heads closely crowded one behind the other is that these rows, in their multiplicity of spindles and winding members facing in the same direction, obscure the view and thereby make checking difficult, and, also, as a result of the crowded construction, access is difiicult in case of failures in operation.

In accordance with the invention, an object thereof is to accommodate as many bobbin heads as possible in a small space. The invention provides better view and improved accessibility of the individual bobbins and of the gear sets without sacrificing the compact design which This is accomplished in a multiple-headed bobbin machine, according to the invention, with bobbin heads situated in one or more tiers, .by having the gear sets of the bobbins along the length of the machine in one row or in several such rows arranged in tiers, one above the other, and, in some cases,

within a row or in tiers alternately opposed to one another, so that the bobbins, as has hitherto been usual only in double-row winding machines, project at both sides of the machine.

In the further development of the idea of the invention, the arrangement may be made in such a way that the bobbin heads or their gear sets lie at an angle to the length of the machine.

In this manner the overall view and the accessibility of the individual bobbins and of the gear sets is considerably improved, with a specially good utilization of space. Because each bobbin projects freely for a certain distance from the contour of the machine frame with respect to the neighboring bobbins. and accordingly, is accessible not only from the front but also from the side, it is possible to move the bobbin heads or their gear sets closer together and accomplish further economies of space.

With this arrangement carried out at an angle to the length of the machine, the gear sets can, in turn, be arranged in succession in a row or in several rows in tiers one above the other, and, in fact, within a row or in tiers they may be arranged in opposition. The size of the angle is governed essentially by the relation of the length of the gear set to the bobbin. At a relationship of 1:1 it will amount, advantageously, to 45 with respect to the longitudinal direction of the machine frame. If the bobbin is smaller in relation to the gear set, then the angle is larger; if, on the other hand, the bobbin is larger, then the angle should be made smaller.

According to the foregoing, the most diverse possibilities are yielded for an advantageous, clear-view and spacesaving arrangement and grouping of the bobbin locations. Thus, for example, it is even possible to arrange the gear sets lying at an arbitrary angle to the length of the machine in pairs, staggered in relation to their bobbin locations, or to arrange them in several such rows in tiers one over the other, in such a way that then the bobbin locations protrude from the machine alternately to the one side and to the other. In this manner a further saving of space can be achieved.

Finally, with the compact design of bobbin heads lying close together, the gear sets can be accommodated in each case in groups or in one common housing, so that the driving and control mechanisms may be grouped together and, furthermore, there is a saving in the weight of the machine. A

In the drawing, several examples of execution are schematically represented.

Fig. 1 shows a multiple-bobbin head winding machine with gear sets mounted in a successive row, arranged in alternating opposition;

Fig. 2 shows a multiple-bobbin head, tiered winding machine with several gear sets arranged in several rows, one above the other, in opposition in a checkerboard pattern;

Fig. 3 shows a multiple-bobbin head, tiered winding machine with gear sets arranged in several individual rows one above the other, in opposition by tiers;

Figures 4 through 6 are the schematic representation of Figures 1 through 3 in plan;

Fig. 7 shows in plan a multiple-bobbin head winding machine similar to that of Fig. 1, in which the gear sets are arranged at an angle to the length of the machine;

Fig. 8 shows in plan a multiple-bobbin head, tiered winding machine similar to that of Fig. 2, in which the gear sets are arranged at an angle to the length of the machine;

Fig. 9 shows in plan a multiple-bobbin head, tiered Winding machine, similar to that of Fig. 3, in which the gear sets are arranged at an angle to the length of the machine;

Fig. 10 shows a multiple-bobbin head winding machine in which two rows, situated one above the other similar to Fig. 9, are united in one row, so that a herring-bone grouping of the gear sets, arranged in staggered pairs, results; and,

Fig. 11 shows a multiple-bobbin head winding machine, in which the superimposed rows similar to Fig. 8 are combined in one row and the gear sets, likewise arranged in staggered pairs, are enclosed in a common housing.

Broadly speaking, the multiple-bobbin head winding longitudinal axis of the frame.

are at an acute angle with respect to the longitudinal axis of the machine frames.

Referring now to the drawings, the bobbin heads are mounted on machine frame 20 and consist of the gear sets 22 and the bobbins proper 24 and 24". The numeral 24 indicates the bobbins of the upper tier of the machine and 24' those of a lower tier or tiers. The original thread-winding bodies 26 supply the thread to be wound through gate brakes 28, which are thread-tensioning devices, and reciprocating traveller mechanisms 33, which distribute the thread in even layers over the bobbins 24 and are driven by gear connections with the gear sets 22 of the bobbin heads in a manner well known in the art. Figures 1, 4 and 7 show the arrangement of multiple-headed bobbin machines with gear sets mounted in succession in a row, alternately opposed. Figures 2, and 8 show the mounting of several such individual rows in tiers one above the other. Figures 3, 6 and 9 show the arrangement of gear sets with the bobbin locations lying in the same direction within a row, but opposed by tiers.

In Fig. 9, the gear sets 22 are mounted not only at an angle to the length of the machine, but also at an angle to one another; it is also possible to mount the gear sets at an angle to the length of the machine only, so that the sets in rows one above the other have the same axial direction, but have the bobbin locations opposed. In the last case, the employment of identical bobbin heads is possible, whereas the bobbin heads of the opposite direction, as, for example, according to Figure 9, require a mirror-image construction.

Another arrangement of the multiple bobbin heads is illustrated in Fig. 10, wherein the staggering of the bobbin heads on the machine frame 20 is achieved by placing the rear edge of each gear set 22 in contact with a side of the gear set immediately preceding to provide a herringbone pattern of the gear sets on the machine frame. The bobbin heads are, thus, arranged in staggered pairs, one bobbin head of each pair extending from one side of the frame and the other from the other side of the frame, to form a row composed of two horizontal lines of bobbin drive means extending along the longitudinal axis of the frame. One line is composed of parallel bobbin gear sets extending from one side of the frame 20 and projecting toward one end of the frame to form an acute angle with the longitudinal axis of the frame. The other line of parallel bobbin gear sets extend from the opposite side of the frame and project toward the same end of the frame as the gear sets in the firstmentioned line to also form an acute angle with the This arrangement provides a herringbone arrangement of the gear sets 22 and associated bobbins 24, whereby the bobbins of longitudinally adjacent gear sets 22 alternately project from opposite sides of the frame 29.

In the examples represented in the figures, all the bobbin heads are equipped with individual drive. The bobbin heads, may, however, be powered in groups or all in common.

The examples of arrangements represented offer the possibility of moving the bobbin heads with their gear sets so close together that each individual bobbin head no longer represents an independent set and several or all of the bobbin heads can be accommodated in over-all housings with drive by groups or over-all drive.

The employment of such novel groupings of bobbin heads is not restricted only to the various needs of winding operations, but may be employed to similar advantage for other purposes as well, as, for example, for the production and after-treatment of rayon threads in a continuous operation.
